You use servers to connect to the Internet. You will have a main server that you use all the time, such as MSN or your local cable or telephone company. In most cases you will never need to change this server connection. However, if you ever need to temporarily connect to the Internet through another source, the temporary server is known as a proxy. Reasons for needing to connect to the Internet via a proxy server are many and varied. If you should ever need to do this, you must configure Internet Explorer to use a proxy server.
